Google Instant Previews, a feature that lets you evaluate search results without clicking through, is now available on mobile for Android (2.2+) and iOS (4.0+) devices across 38 languages. Just like the desktop version of Google Instant Previews, you can now visually compare search results using webpage snapshots, which is particularly useful when you know what the content you're trying to find looks like.
To use Google Instant Previews on your mobile device, all you have to do is make a search on google.com and tap on the magnifying glass next to any search result. A side-by-side comparison view of the webpage previews for the first page of search results will appear. When you find a result you like, tap on the preview to go straight to the website. When there is a mobile version of a website available, Google makes a point to show a preview of the mobile page.
Google has created a video to promote the feature:
Google first launched Instant Previews for the desktop back in November 2010. While I see how it could be useful, I have personally never bothered using the feature. Have you given it a shot, and if so, what was your experience?
